Socio-environmental impacts caused by hydroelectric dams in northeastern Brazil / Impactos socioambientais causados por barragens hidrelétricas no nordeste do Brasil

With the advancement of the energy sector in Brazil there was a large insertion of hydroelectric dams, many were installed in the northeast due to the great availability of water resources, thus being one of the main reasons for environmental and social impacts. The work seeks to warn about the socioenvironmental damage in the Northeastern region of Brazil caused by hydroelectric dams today. For the research were used 18 articles, analyzed quantitatively and qualitatively, always seeking data consistently and respecting the research line. After analyzing 13 hydroelectric dams, several social and environmental impacts were observed, such as floods, impacts on local fauna and flora, relocation of people, loss of culture and economic impacts. It has been observed that for decades human action as an intervener has caused numerous damage to the environment and society, as a consequence there has been a noticeable change in the surrounding regions in climate, economic and social advancement of people, as a solution the work suggested the use of new methods for the production of electricity, so that the impacts are smaller and viable to the economy, preserving the environment and the production of electricity.
